Sealing and Insulating Your Crawl Space

Crawl Space Insulation with DBS

If you have issues with cold and drafty floors in the winter and musty smells in the summer, your crawl space could be to blame. At DBS, our goal is to help you achieve whole-home comfort by transforming your musty crawl space. Warmer rooms, lower energy bills, and cleaner air are all possible with our expert crawl space encapsulation service.

Crawl Space Air & Moisture Sealing

At first mention, ventilation beneath your home sounds like a good thing. But the result often leads to energy inefficiency. When air freely enters your crawl space, it then travels throughout the rest of your home. In the winter, cold air seeps through vents, gaps, and cracks in your foundation or rim joists. The result is cold floors in your home’s main level, and high heating bills to fix the issue.

During summer months, hot and humid air enters the crawl space. Spending money to constantly cool the air increases your energy spend once again. Furthermore, excess moisture in dirt spaces encourages mold and mildew growth. Because more than 50% of the air you breathe in your home originates from your basement or crawl space, it is important to regulate that air quality. 

DBS uses CleanSpace®, a durable poly sheet material, that makes an excellent cover for dirt crawl spaces. It is applied on top of a drainage matting, to provide the ultimate protection against moisture build-up. We also recommend always air sealing the rim joists and duct sealing to minimize air leakage and reduce heating and cooling costs year-round. We help hundred of homeowners each year by applying closed-cell spray foam to air seal and insulate rim joists.

Not only is it important to protect your crawl space from air and moisture, but it is essential to insulate. Home and cabin owners from our service area of Minnesota and Wisconsin often call to complain of cold floors and issues with frozen pipes. Whether near outer walls in the kitchen or beneath the home, frozen pipes are a huge hassle and can cause lots of damage.

To prevent issues like freezing pipes and cold floors, DBS recommends encapsulating your crawl space with TerraBlock™. This 3/4" thick foam is waterproof, resists punctures and tearing, and does not support mold, rot, or mildew growth. Our expert team installs this insulation between a layer of drainage matting and vapor barrier, as illustrated in the image to the right.

As a result, your crawl space is protected with a vapor barrier and has a thermal break from the cold dirt ground.

Year-Round Benefits of Crawl Space Encapsulation

Insulating your crawl space saves you money on heating and cooling bills year-round. Elimating mildew from your crawl space prevents mold spores from circulating and degrading your air quality. Finally, a dry and protected crawl space means that it is available for you to use for storage.
